Abstract

The present study is related to elucidating the remote sensing monitoring and capabilities for profiling to particulate matter (PM) mass concentration control in the lowest atmospheric layers. The PM was studied at a distance of 5.5 km from the LIDAR station. The experiments were conducted in May and October 2020 in the South-Eastern part of the Bulgarian capital Sofia during a COVID-19 lockdown. The LIDAR measurement data was compared during the experiments with in situ sampling by mobile devices located just below the spot of the LIDAR beam: (i) Absorber collects particles higher than 3 μm;(ii) PM Microcollector type SDS 011;and (iii) Andersen Cascade Impactor for exploring PM size distribution and microbiota. The results obtained show that remote sensing can be very effective when quantitative evaluation has been combined with in situ sampling for PM qualitative assessment. © 2021 Academic Publishing House.

城市地区低层大气颗粒物的激光雷达监测和原位采样

本研究旨在阐明遥感监测和对大气低层颗粒物(PM)质量浓度控制的能力。PM在距离激光雷达站5.5公里处进行研究。这些实验是在2019冠状病毒病封锁期间于2020年5月和10月在保加利亚首都索菲亚东南部进行的。在实验过程中，将激光雷达测量数据与位于激光雷达光束点下方的移动设备的原位采样数据进行了比较:(i)吸收器收集大于3 μm的颗粒;(ii) SDS 011型PM微收集器;(iii) Andersen级联冲击器用于探索PM尺寸分布和微生物群。结果表明，将遥感定量评价与现场采样相结合，可以有效地进行PM定性评价。©2021学术出版社。版权所有。
